Simplifying f(x) = (x + 2) * 3 Multiply f * x fx = (x + 2) * 3 Reorder the terms: fx = (2 + x) * 3 Reorder the terms for easier multiplication: fx = 3(2 + x) fx = (2 * 3 + x * 3) fx = (6 + 3x) Solving fx = 6 + 3x Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Divide each side by 'x'. f = 6x-1 + 3 Simplifying f = 6x-1 + 3 Reorder the terms: f = 3 + 6x-1
